Joseph C Diorio

Joseph C Diorio is a one-name plumbing operation at 87 Grovers Ave in Winthrop, and nearly everything on file about it is permits. BuildZoom lists six permitted jobs. Five are plumbing and gas work in Newton between 2016 and 2019 — bathroom and kitchen remodels, first- and second-floor water piping, a cook stove, two furnaces, an oven and a water heater replaced; two of those permits are marked cancelled. The sixth goes back to 2002, plumbing for a room addition in Burlington. The licence is the thing to settle before calling. BuildZoom shows a City of Newton plumber licence, #22360, which it says expired on 1 May 2020 and which it last verified as expired in March 2022; the same number appears again under a Heater Contractor type, also inactive. That is the directory's record rather than a state check — and Massachusetts plumbing work requires a current licence — so ask for the licence number in force today and confirm it with the state plumbing board before any work is scheduled. The useful next step here is references: a couple of recent local jobs you can call, and that current licence number.
